Windows 10 Mobile Insider builds return after big PC and tablet push

Microsoft announced that it has started rolling the latest preview build of Windows 10 Mobile to people within its Insider program.

Dubbed Build 10512, this latest beta version of the Windows 10 mobile operating system includes several quality of life improvements, including a boost to overall performance and stability, the ability to set a lock screen background from within the Photos app and a new, less aggressive shape writing algorithm.

Check out the full list of improvements below:

• General improvement in overall stability and performance.
• You can now set the Lock screen and background image from within the Photos app.
• We fixed an issue where apps installed on SD cards weren’t working after a reboot.
• We have improved Latvian and Chinese inputs.
• We have made improvements to the Kid’s Corner tile layout.
• We have improved reliability of Data Sense notifications.
• Modified Shape Writing algorithm to be less aggressive in suggesting contact names over common words.
• Resolved an issue where Camera would not launch when the phone was locked.
• We fixed an issue where notifications for incoming text messages weren’t appearing.
• We fixed an issue where the touch screen wouldn’t be responsive after ending a phone call on some devices.
• And we fixed an issue where folder tiles have obviously overlapping text.

Of course, as with any beta build, there are also several issues that have made their way into 10512:

• Mobile hotspot doesn’t work in this build. When sharing the Internet from your phone using Mobile Hotspot, devices will fail to get a valid IP address from your phone and will show no internet access.
• Two-factor authentication for your MSA with a phone number doesn’t work in this build. If you reset your phone and go through the first run experience, you won’t be able to input more than 2 characters for validating phone or text authentication. If you have a secondary email for two-factor authentication – you can choose that. As a workaround, add secondary email for two-factor authentication.
• Some phones might spend a long time in the post update migration experience – just let the phone sit and it should complete this migration.
• Apps that use background audio such as Groove, Podcast, Pandora, etc. will crash when launching after receiving an app update from the Store. Rebooting the device will resolve this issue.
• Some phones with a large number of tiles pinned to the Start screen may get stuck in a state where the device shows “Loading…”; the device will need to be reset or rolled back to Windows Phone 8.1 using Windows Phone Recovery Tool.
• Some apps may fail to update through the Store with the error code 0x80073cf9; uninstalling the application and reinstalling it will resolve this issue.
• The Movies & TV app will not work in this build (video playback is currently broken).

Based on the above change log, it appears that Microsoft is making good progress towards a final release, though the operating still might not be released before November.
